SHOCK-ABSORBER.

To all ufwm it may concern:

Be it known that I, ALEXIS RPRIBIL, a citizen of the United States, and a resident of Detroit, inthe county of Wayne 'and State of Michigan, have invented a new `and useful Shock-Absorber, of which the following is a specification.. y

This invention has for its object the production of a shock absorber particularly applicable for motor vehicles having a three point suspension spring, that is, a spring the vehicle and connected at its opposite ends to the running gear and intermediate to the ends of the body of the vehicle; and the invention consists in the novel combinations and constructions hereinafter set forth and claimed.

In describing thisinvention, reference is had to the accompanying drawings, in which like characters designate corresponding parts in all the views.`

Figure 1 is a rear elevation of a motor car embodying my invention, parts being omitted.

Fig. 2 is an enlarged sectional view on line A-A, Fig. 1. y i

Fig. 3` is `an enlarged sectional view through the bracket connected to the differential gear casing, contiguous partsbeing also shown. .s t A Y Y' Fig.- 4 is an elevation, partly in section, looking to -theright in Fig.v 3.` y

Figs. 5 "and 6` are detail views of the bracket-'connected tothe body of the `vehicle. Vj, .n

1 is the sprinfr which extends transversely of the vehicle a fove the rear axle and which is connectedn at its opposite ends tothe running gear, as the rear axle unit, and inf termediate of its ends to the body of the vehicle. ,v n. V

I have here shown'my invention as applied to an Ford car in which the spring 1 is connected at its opposite ends at .2 to shackles 3 pivoted to brackets 4 carried at the opposite ends of the rear axle, and is xed intermediate of its ends to a channel bar or spring seat 5 rigidly secured to the body or chassis 6, it being secured to said sprin seat byarbolt 7 extending 'trans- ,verse y through`- the springand by clips 8 extending around the s ring seat 5 and the intermediate portion o the spring4 l. n y n ',The rear axle construction includes the usual casings .9 -uclosing the liveshaft sec- Specication of Letters Patent.

tions of the axle and the sections 10 of the differential gear casing, the latter being located between opposing ends of the casings 9. The sections l0 of the dierential gear casing have lapping peripheral anges and lugs l1 and 12 and are secured together by bolts 13 extending transversely through the lugs 12.

The foregoing constructions in themselves form no part of my invention.

The shock absorbing means is located be* tween the ends of the spring 1 and usually centrally of the vehicle in a transverse direction, and is connected to the axle and to the body or portion of the spring rigid with the body, and includes a bracket connected to the axle, a bracket for connection to the car body, and shook preventing means connecting the brackets. The shock preventing means preferably includes members arranged to prevent direct shocks as Well as indirect, as those due to rebound of the sprin 14 designates the bracket connected to the axle, and here shown as mounted on the differential gear casin and having side flanges l5, which lap the anges and lugs 11 and 12 of the sections 10 of the differential gear casing, the flanges 15 being formed with openings 16 designed to come into alinement with the bolt openings through the flanges and lugs 11 and 12 which said flanges lap, in order to be secured in position by the bolts 13. The edges of the anges 15 are concave to conform to the curvature of the differential gear casing. The bracket 14 is preferably located on the rear side of the diiferential gear casing.

. 17 designates the bracket secured to the body or chassis 6 and fixed relatively to the body frame and the central part of the spring 1, the bracketl 17 being here shown in the form of a channel and extending under the intermediate part of the spring 1 with the bottomrof its channel engaging the underside of the spring and the lower edges of the spring seat 6, and with its channel facing downwardly. The bracket 17 is fixedly secured relatively to the spring and spring seat by a clip 18 embracing the spring seat and extending at its opposite ends through suitable holes 19 in the brackets 17 and on which turn nuts 20 against the inner face of the bottom of the channel` In placing the bracket 17 in posif opposite directions on the rod and thel bracket114.`^*'The rod is pivoted"at"'24"at its upper end between the `sides of the bracket 17 and extends downwardly through a passage formed in the bracket 14, therod having a shoulder 25 near its upper end and a shoulder 26 at its lower end, the latter being `a nut threading onthe lower end of the rod.4

27 is a direct shock resisting spring interposed between the shoulder25 and the bracket 14. 28 is an indirectshoclcor re bound preventing spring interposed between the shoulder 26 and the bracket 14. As here shown, the opposing ends of the` springs bearfagainst abutments'29 slidable horizontally in the passage in the bracket 14 and* bearing against stops or braces 30 extending transversely through the passage of the bracket lain the front and the rear of the rod 23, the stops having sleeves 31 on which the abutments bear. The abutments `are horizontally slidable'inorder to permit the rod 23 to tilt, during the action of the spring 1, about a horizontal axis located between the ends ofthe rod 23. The abutments 29 are bent up U shape in cross sectionfout of sheet Vmetal blanks and have perforations 32 in their intermediate portions throughwhich the rod 23 extends. The brackets 111 and 17 are also lformed out of sheet metal blanks, the bracket 14 being bent to form the oppo's# ing sides or flanges 15 and the passage in which the abutments 29 are located `In motor cars, as the Ford cars, having springs. extending transversely of the"` car and suspended at three points, the spring floats sidewise and as the body is fastened to the center of the rear spring, th'ejbody rolls with the spring.V The side motionis increased when the car is unevenly loaded. In use, my shock absorber steadies the body frame of the car and alleviates the rebound action. When the main or rear spring is deflected, the upper or shock receiving spring 27 reinforces and steadies the main spring, and when the main spring moves back toward `its normal position, the rebound spring28 slows up the movement gradually until the main sprinor is in its normal position. This shock absorber is particularly advantageous in that it is particularly simple and economical in construction and can be readily applied to cars to which it is designed to be applied.
